摘要
基于UPFC( 统一潮流控制器) 的动态模型,提出以受控线路有功和无功偏差、受控节点电压幅值偏差、UPFC 两侧不平衡有功偏差、UPFC 直流侧电容电压偏差、发电机的有功输出偏差和发电机转子的角速度偏差七个可测量为状态反馈量,设计了UPFC的线性最优控制系统。仿真结果表明,所设计的控制系统可以有效地控制节点电压和线路潮流,改善系统的暂态稳定性。
This paper is based on dynamic model of UPFC, and its linear optimal controller are established by using reactive power increment of controlled line active、voltage increment of controlled bus、imbalance active power of UPFC、DC capacitance voltage increment of UPFC、output active power increment and rotor speed increment of generator as state variables. The effects for enhancing the stability and dynamic performance of power system and controlling bus voltage and line power flow are illustrated by simulation on a one machine infinite bus system. It manifests the validity and significant advantages of the design approach proposed in this paper.
